Hesperin

Primary human umbilical vein endothelial cells (HUVECs) are cultured in collagen-coated tissue-culture dishes in an atmosphere containing 95 % air and 5 % CO₂. Human monoblast U937 cells are grown in RPMI-1640 medium with 10 % fetal bovine serum, 10 U/mL Penicillin, and 10μg/mL Streptomycin. HUVECs are cultured in collagen-coated 96-well plates as confluent monolayers. Hesperin is added into wells at the indicated final concentrations (0-30 μg/mL) and then incubated for 24 h. Cell viability is measured by cell counting kits^[2].

Mice^[1] A colony of wild-type and Nrf2-null mice are backcrossed with C57BL/6 mice for ten generations. All mice are housed in the same animal care facility controlled for temperature, humidity, and light. Seven-week-old male wild-typeand Nrf2-null mice (n=6-8/group) are divided into five groups fed the following diets: 1) a standard diet (AIN-93, containing 4% soybean oil) for 12 weeks and vehicle (1:10 solution of DMSO/PBS) injected intraperitoneally 4 times per week for the last four weeks (control group), 2) a high-fat diet (HFD) (containing 4% soybean oil and 31% lard) for 12 weeks and vehicle injected intraperitoneally 4 times per week for the last four weeks (HFD group),3) a HFD for 12 weeks and Hesperin (10mg/Kg/day; dissolved in 1:10 solution of DMSO/PBS) injected intraperitoneally 4 times per week for the last four weeks (HFD+ Hesperin), 4) a HFD for 6 weeks followed by a HFD containing 1% carbonyl iron for 6 weeks and vehicle injected intraperitoneally 4 times per week for the last four weeks(HFD+Iron), and 5) a HFD for 6 weeks followed by a HFD containing 1% carbonyl iron for 6 weeks and Hesperin (10mg/Kg/day) injected intraperitoneally 4 times per week for the last four weeks (HFD+Iron+Hesperin). After 12 weeks, blood samples are collected by cardiac puncture under anesthesia with sodium pentobarbital (50 mg/kg, ip) and livers are harvested and stored at -80°C until analysis^[1].
